2006 Toyota Vitz/Yaris water pump — what it does and when to replace it

A water pump is absolutely fitted to the 2006 Toyota Vitz/Yaris (XP90 series). Toyota’s engine repair manuals for the 1KR‑FE (1.0L), 2SZ‑FE (1.3L) and 1NZ‑FE (1.5L) engines list inspection and replacement procedures for the “Engine Water Pump,” and Toyota’s Electronic Parts Catalogue shows the pump assembly, gasket/O‑ring and related hardware for these engines. These technical sources confirm the water pump is a standard, belt‑driven coolant pump on this model.

On a 2006 Vitz/Yaris, the water pump keeps coolant moving through the block, head and radiator so engine temps stay in the sweet spot. Without it, the little Toyota would overheat quickly, especially in stop‑start city driving. The pump is mechanically driven by the auxiliary (serpentine) belt, not the timing chain, so it spins any time the engine’s running.

As part of routine servicing, the pump deserves a look whenever coolant is changed or a belt is replaced. Toyota specifies Super Long Life Coolant (pink, premixed)
